Abstract
A multiple row sugar cane harvester having automatic and independent control of multiple base cutters utilized to severe sugar cane stalks in adjacent rows. Position sensors sense the height of the base cutters relative to the chassis of the sugar cane harvester and feed the signals to a controller for adjusting the height to a preselected level. The base cutters are individually driven by hydraulic motors through individual hydraulic circuits and the operating pressure is sensed and fed to the controller for determining whether a choke condition exists. A load sensor is incorporated between the linkage and the sugar cane harvester chassis for determining whether the base cutters have ground contact to elevate the base cutters.

Embodiment
Fig. 1 shows cane harvester 10, and described cane harvester 10 comprises frame 12, and described frame 12 has endless track 14, and described endless track 14 is for providing power for the directed movement on field 16.Frame 12 provides power by the engine (being generally internal combustion engine) of appropriate format.Endless track 14 is provided in the motion on field 16 and turns to.To those skilled in the art, it is evident that frame 12 can adopt the device of various different propulsion unit and ground motion (such as taking turns), to enable grain header at field overground locomotion to gather in sugarcane.
Topping unit assembly 18 extends forward from frame 12, to cut off the top of cane stalk, thus contributes to harvesting.Crop row separator assembly 20 comprises pair of rolls, and crop is separated and cane stalk is moved along downstream direction relative to the propulsion of frame 12 by this pair of rolls, wherein, is cut the base portion of cane stalk by pair of discs cutting component 22.Disc cutter assembly 22 is made up of the rotating disc of overlap usually, and cane stalk is fed in the rotating disc of described overlap, to cut off cane stalk at its base portion place.The cane stalk cut off moves to feed mechanism 24 together with unwanted material along downstream direction, these blanks are transported to the overall equipment represented by Reference numeral 26 by described feed mechanism 24, described equipment 26 is cleared up unwanted material and other crop fragment and is extracted other waste material, to become to be sent to certain form of crop transport vehicle (not shown) by their final disposals by transveyer 27 from blank.
The cane harvester of Fig. 1 and Fig. 2 is the grain header being suitable for processing multirow (being such as illustrated as process two row) sugarcane.For this reason, cane harvester has paired left and right disc cutter 22, controls the independence of the cutting-height of disc cutter to provide.Except can relative to except bottom offset on the surface in field 16, disc cutter 22 be driven by the hydraulic motor 28 schematically shown in Fig. 2 and Fig. 5.
In Figure 5, each hydraulic motor 28 drives corresponding paired disc cutter 22.Left side motor 28 is hydraulically connected to hydraulic pressure source 30 by the pipeline 34 in hydraulic motor 28, and right hydraulic motor 28 is connected to the hydraulic fluid source 32 that can independently control via pipeline 36.As mentioned below, pressure sensor 38 and pipeline 34 and sensor 40 and pipeline 36 sense motor pressure.This motor pressure is delivered to electronic control unit (ECU) 46 by circuit 42 and 44 in the form of a signal.
Motor 28 and disc cutter 22 can pass through left side mechanical interconnection device 48 and right side mechanical interconnection device 50 mechanically upper and lower displacement.The displacement of motor 28 and disc cutter 22 is sensed by left-hand side part 52 and right side members 54.Via circuit 56 and 58, the signal from these parts is also delivered to ECU46.Sensor 52 and 54 can adopt multiple multi-form in one, but in this example, they can be hall effect sensors, and the suspension of described hall effect sensor test disks cutter rotates, and produces the signal representing disc cutter height thus.In addition, the mechanically interconnected device 48 and 50 for hydraulic motor and disc cutter can comprise load transducer 60 and 62, and described load transducer 60 and 62 is for interconnection between the linkage of disc cutter and the frame 12 of grain header 10.Signal from load transducer 38 and 40 is fed to ECU46 by circuit 42 and 44.
Sensor 38 and 44 detects the operating pressure of motor 28 and detects the operating pressure of motor 28 as mentioned below and when increase above threshold value (such as when running into ground and blocking).Sensor 52 and 54 produces the signal proportional with the distance of disc cutter 22 more than surface, field.This is used as mainly to input with the position determining disc cutter 22.The load transducer 60 and 62 such as soil connecting state of detection between disc cutter 22 and surface, field when load vanishing of use can be suspended.
Fig. 3 shows the partial side view of in one group of disc cutter one suspension system 48 used.This suspension system is identical for another in disc cutter.Suspension system comprises the hinge connector 68 that pivotable is connected to the framing component of frame 12.Load pin sensor 60 is positioned in described hinge connector.Actuator 70 has the end being connected to hinge connector 68 and the output shaft 72 be connected to for the hoisting mechanism of disc cutter.The displacement transducer 52 being illustrated as hall effect sensor is arranged in bracket 74, and described bracket 74 is also connected to the frame element of frame 12.
Fig. 4 is the end view of another part of grain header, it illustrates the additional aspects of the row separator 20 be also arranged in frame 12, and wherein, graphic actuator 70 and be connected output shaft 72 are in order to raise or to reduce disc cutter 22 and hydraulic motor 28.The connecting rod 71 and 73 of general parallel orientation is pivotally connected to frame 12 and forms the structural member of row separator 20 and disc cutter 22.Thus, sensor 52 and 54 detection angles changes, the change of the distance on described angle change reflection disc cutter and surface, field.
System as above operates in the mode described in appended supplementary document.The arrangement of sensor and be keep the height of disc cutter independent of being in optimum preset value each other with the direct effect that ECU interconnects.Load transducer 60 and 62 determines disc cutter whether colliding surface and correspondingly regulate this mechanism in mode upwards in use.Similarly, the operating pressure that pressure sensor 38 and 40 detects when Yin Mada 28 significantly increases and occurs the situation that ground is blocked.Displacement transducer 52 determines height relative to ground and according to the logic stated in appended document independent of the height keeping disc cutter each other with pre-selected pattern.
Although describe the present invention at least one embodiment, the present invention further can revise within spirit and scope of the present disclosure.Therefore, the application is intended to contain any one modification of its general principle of use of the present invention, purposes or modification.In addition, the application is intended to contain these change schemes of the present disclosure, and described change scheme is the change scheme fallen in the scope of the known of field belonging to the present invention or conventional practice and the change scheme fallen in the limited range of claims.
